### AsmTK Configuration Variable Setup

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Sets default paths for AsmTK and AsmJIT, and configures build-related boolean variables like ASMJIT_EXTERNAL, ASMTK_EMBED, and ASMTK_STATIC. These variables are exposed as CACHE variables for user configuration.

```cmake
if (NOT DEFINED ASMTK_DIR)
  set(ASMTK_DIR "${CMAKE_CURRENT_LIST_DIR}")
endif()

if (NOT DEFINED ASMJIT_DIR)
  set(ASMJIT_DIR "${ASMTK_DIR}/../asmjit")
endif()

if (NOT DEFINED ASMJIT_EXTERNAL)
  set(ASMJIT_EXTERNAL FALSE)
endif()

if (NOT DEFINED ASMTK_EMBED)
  set(ASMTK_EMBED FALSE)
endif()

if (NOT DEFINED ASMTK_STATIC)
  set(ASMTK_STATIC ${ASMJIT_EMBED})
endif()

set(ASMTK_DIR    "${ASMTK_DIR}"  CACHE PATH "Location of 'asmtk'")
set(ASMJIT_DIR   "${ASMJIT_DIR}" CACHE PATH "Location of 'asmjit'")

set(ASMJIT_EXTERNAL ${ASMJIT_EXTERNAL} CACHE BOOL "External 'asmjit'")

set(ASMTK_TEST   ${ASMTK_TEST}   CACHE BOOL "Build 'asmtk' test applications")
set(ASMTK_EMBED  ${ASMTK_EMBED}  CACHE BOOL "Embed 'asmtk' library (no targets)")
set(ASMTK_STATIC ${ASMTK_STATIC} CACHE BOOL "Build 'asmtk' library as static")
```

### CMake Project Initialization and Policy

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Sets the minimum CMake version required and pushes/sets CMake policies for consistent behavior, specifically honoring visibility properties.

```cmake
cmake_minimum_required(VERSION 3.8)

cmake_policy(PUSH)
cmake_policy(SET CMP0063 NEW) # Honor visibility properties.
```

### Parse Assembly with AsmParser and Dump Code (C++)

Source: https://github.com/asmjit/asmtk/blob/master/README.md

Demonstrates using AsmParser to parse assembly instructions and emit them to a BaseEmitter, with a helper function to dump the generated binary code in hexadecimal format. It utilizes AsmJit's environment, CodeHolder, and x86::Assembler.

```c++
#include <asmtk/asmtk.h>

using namespace asmjit;
using namespace asmtk;

// Used to print binary code as hex.
static void dumpCode(const uint8_t* buf, size_t size) {
  constexpr uint32_t kCharsPerLine = 39;
  char hex[kCharsPerLine * 2 + 1];

  size_t i = 0;
  while (i < size) {
    size_t j = 0;
    size_t end = size - i < kCharsPerLine ? size - i : size_t(kCharsPerLine);

    end += i;
    while (i < end) {
      uint8_t b0 = buf[i] >> 4;
      uint8_t b1 = buf[i] & 15;

      hex[j++] = b0 < 10 ? '0' + b0 : 'A' + b0 - 10;
      hex[j++] = b1 < 10 ? '0' + b1 : 'A' + b1 - 10;
      i++;
    }

    hex[j] = '\0';
    puts(hex);
  }
}

int main(int argc, char* argv[]) {
  // Setup CodeHolder for X64.
  Environment env(Arch::kX64);
  CodeHolder code;
  code.init(env);

  // Attach x86::Assembler to `code`.
  x86::Assembler a(&code);

  // Create AsmParser that will emit to x86::Assembler.
  AsmParser p(&a);

  // Parse some assembly.
  Error err = p.parse(
    "mov rax, rbx\n"
    "vaddpd zmm0, zmm1, [rax + 128]\n");

  // Error handling (use asmjit::ErrorHandler for more robust error handling).
  if (err != Error::kOk) {
    printf("ERROR: %08x (%s)\n", err, DebugUtils::errorAsString(err));
    return 1;
  }

  // Now you can print the code, which is stored in the first section (.text).
  CodeBuffer& buffer = code.section_by_id(0)->buffer();
  dumpCode(buffer.data(), buffer.size());

  return 0;
}

```

### Define AsmTK Source Files and Add to Target

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

This CMake function, `asmtk_add_source`, collects source files from a specified base directory and adds them to a list that will be used to build the AsmTK library. It also groups the source files for better organization within the build system.

```cmake
function(asmtk_add_source out base_dir)
  set(src_array)
  foreach(file ${ARGN})
    set(src_file "${ASMTK_DIR}/${base_dir}/${file}")
    list(APPEND src_array ${src_file})
  endforeach()
  source_group(TREE "${ASMTK_DIR}" FILES ${src_array})

  set(out_tmp ${${out}})
  list(APPEND out_tmp ${src_array})
  set("${out}" "${out_tmp}" PARENT_SCOPE)
endfunction()

set(ASMTK_SRC "")
set(ASMTK_SRC_LIST
  asmtk/asmtk.h
  asmtk/asmparser.cpp
  asmtk/asmparser.h
  asmtk/asmtokenizer.cpp
  asmtk/asmtokenizer.h
  asmtk/elfdefs.h
  asmtk/globals.h
  asmtk/parserutils.h
  asmtk/strtod.h
)
asmtk_add_source(ASMTK_SRC src ${ASMTK_SRC_LIST})
```

--------------------------------

### Configure AsmTK Library Target

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

This section defines the 'asmtk' library target using `add_library`. It sets the C++ standard to C++17, applies various compile options based on configuration (Debug, Release), and links against the AsmJit library. It also configures include directories and sets C++ visibility.

```cmake
if (NOT ASMTK_EMBED)
  add_library(asmtk ${ASMTK_TARGET_TYPE} ${ASMTK_SRC})
  target_compile_features(asmtk PUBLIC cxx_std_17)
  target_compile_options(asmtk PUBLIC ${ASMTK_CFLAGS})
  target_compile_options(asmtk PRIVATE ${ASMTK_PRIVATE_CFLAGS}
    $<$<CONFIG:Debug>:${ASMTK_PRIVATE_CFLAGS_DBG}> 
    $<$<NOT:$<CONFIG:Debug>>:${ASMTK_PRIVATE_CFLAGS_REL}>)

  if(ASMJIT_EXTERNAL)
    target_link_libraries(asmtk PUBLIC ${ASMJIT_LIBRARY})
    find_path(ASMJIT_INCLUDE_DIR NAMES asmjit/core.h)
    target_include_directories(asmtk PRIVATE ${ASMJIT_INCLUDE_DIR})
  else()
    target_link_libraries(asmtk PUBLIC asmjit::asmjit)
  endif()

  target_include_directories(asmtk BEFORE INTERFACE 
          $<BUILD_INTERFACE:${ASMTK_INCLUDE_DIRS}>
          $<INSTALL_INTERFACE:${CMAKE_INSTALL_INCLUDEDIR}>)

  set_property(TARGET asmtk PROPERTY CXX_VISIBILITY_PRESET hidden)

  # Add asmjit::asmtk target (alias to asmtk).
  add_library(asmjit::asmtk ALIAS asmtk)
  # TODO: [CMAKE] Deprecated alias - we use projectname::libraryname convention now.
  add_library(AsmTK::AsmTK ALIAS asmtk)

  # Add AsmTK install instructions (library and public headers).
  if (NOT ASMTK_NO_INSTALL)
    install(TARGETS asmtk
            EXPORT asmtk-config
            RUNTIME DESTINATION "${CMAKE_INSTALL_BINDIR}"
            ARCHIVE DESTINATION "${CMAKE_INSTALL_LIBDIR}"
            LIBRARY DESTINATION "${CMAKE_INSTALL_LIBDIR}"
            INCLUDES DESTINATION "${CMAKE_INSTALL_INCLUDEDIR}")
    install(EXPORT asmtk-config
            NAMESPACE asmjit::
            DESTINATION "${CMAKE_INSTALL_LIBDIR}/cmake/asmtk")

    foreach(_src_file ${ASMTK_SRC_LIST})
      if ("${_src_file}" MATCHES "\.h$" AND NOT "${_src_file}" MATCHES "_p\.h$")
        get_filename_component(_src_dir ${_src_file} PATH)
        install(FILES "${ASMTK_DIR}/src/${_src_file}" DESTINATION "${CMAKE_INSTALL_INCLUDEDIR}/${_src_dir}")
      endif()
    endforeach()
  endif()

  if (ASMTK_TEST AND NOT ASMJIT_EMBED)
    set(ASMTK_SAMPLES_SRC 
      asmtk_test_x86cmd 
      asmtk_test_x86handler 
      asmtk_test_x86parser)

    foreach(_target ${ASMTK_SAMPLES_SRC})
      add_executable(${_target} "${ASMTK_DIR}/test/${_target}.cpp")
      target_link_libraries(${_target} asmjit::asmjit asmjit::asmtk)
      target_compile_features(${_target} PUBLIC cxx_std_17)
      set_property(TARGET ${_target} PROPERTY CXX_VISIBILITY_PRESET hidden)
    endforeach()
  endif()
endif()

cmake_policy(POP)
```

### AsmTK Compiler Flags Configuration

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Sets common include directories and initializes C++ compiler flags. It includes conditional logic to append specific flags based on the compiler ID (MSVC, GNU, Clang, AppleClang) for optimization, warnings, and other build-specific settings.

```cmake
set(ASMTK_INCLUDE_DIRS "${ASMTK_DIR}/src")       # Include directory is the same as source dir.
set(ASMTK_CFLAGS "")                             # Public compiler flags.
set(ASMTK_PRIVATE_CFLAGS "")                     # Private compiler flags independent of build type.
set(ASMTK_PRIVATE_CFLAGS_DBG "")                 # Private compiler flags used by debug builds.
set(ASMTK_PRIVATE_CFLAGS_REL "")                 # Private compiler flags used by release builds.

if (NOT ASMTK_NO_CUSTOM_FLAGS)
  if ("${CMAKE_CXX_COMPILER_ID}" STREQUAL "MSVC" OR "x${CMAKE_CXX_SIMULATE_ID}" STREQUAL "xMSVC")
    list(APPEND ASMTK_PRIVATE_CFLAGS
      -MP                      # [+] Multi-Process Compilation.
      -GR-                     # [-] Runtime type information.
      -GF                      # [+] Eliminate duplicate strings.
      -Zc:inline               # [+] Remove unreferenced COMDAT.
      -Zc:strictStrings        # [+] Strict const qualification of string literals.
      -Zc:threadSafeInit-      # [-] Thread-safe statics.
      -W4)                     # [+] Warning level 4.

    list(APPEND ASMTK_PRIVATE_CFLAGS_DBG
      -GS)                     # [+] Buffer security-check.

    list(APPEND ASMTK_PRIVATE_CFLAGS_REL
      -GS-                     # [-] Buffer security-check.
      -O2                      # [+] Favor speed over size.
      -Oi)                     # [+] Generate intrinsic functions.
  elseif ("${CMAKE_CXX_COMPILER_ID}" MATCHES "^(GNU|Clang|AppleClang)$")
    list(APPEND ASMTK_PRIVATE_CFLAGS -Wall -Wextra -Wconversion)
    list(APPEND ASMTK_PRIVATE_CFLAGS -fno-math-errno -fno-threadsafe-statics)
    list(APPEND ASMTK_PRIVATE_CFLAGS_REL -O2)
  endif()
endif()
```

--------------------------------

### Deprecated Option Handling for AsmTK

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Handles deprecated build options like ASMTK_BUILD_EMBED and ASMTK_BUILD_STATIC, providing deprecation messages and mapping them to the current options ASMTK_EMBED and ASMTK_STATIC.

```cmake
if (DEFINED ASMTK_BUILD_EMBED)
  message(DEPRECATION "ASMTK_BUILD_EMBED is deprecated, use ASMTK_EMBED")
  set(ASMTK_EMBED "${ASMTK_BUILD_EMBED}")
endif()

if (DEFINED ASMTK_BUILD_STATIC)
  message(DEPRECATION "ASMTK_BUILD_STATIC is deprecated, use ASMTK_STATIC")
  set(ASMTK_STATIC "${ASMTK_BUILD_STATIC}")
endif()
```

--------------------------------

### AsmJIT Dependency Handling

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Conditionally includes the AsmJIT CMakeLists.txt or uses find_package(asmjit CONFIG REQUIRED) based on the ASMJIT_EXTERNAL variable. If AsmJIT is not external, it appends AsmJIT's CFLAGS to AsmTK's private CFLAGS.

```cmake
if (ASMJIT_EXTERNAL)
  find_package(asmjit CONFIG REQUIRED)
else()
  include("${ASMJIT_DIR}/CMakeLists.txt")
  list(APPEND ASMTK_PRIVATE_CFLAGS ${ASMJIT_CFLAGS})
  list(REMOVE_DUPLICATES ASMTK_PRIVATE_CFLAGS)
endif()
```

--------------------------------

### CMake Project Definition

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Defines the project name as 'asmtk' and specifies C++ as the language. It includes logic to prevent re-defining the project if it has already been created, which is useful for embedded projects.

```cmake
if (NOT CMAKE_PROJECT_NAME OR "${CMAKE_PROJECT_NAME}" STREQUAL "asmtk")
  project(asmtk CXX)
endif()
```

--------------------------------

### AsmTK Static Flag Inclusion

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Appends the '-DASMTK_STATIC' preprocessor definition to ASMTK_CFLAGS and ASMTK_PRIVATE_CFLAGS if AsmTK is configured to be embedded or static. This ensures the correct build configuration is reflected during compilation.

```cmake
if (ASMTK_EMBED OR ASMTK_STATIC)
  List(APPEND ASMTK_CFLAGS         "-DASMTK_STATIC")
  List(APPEND ASMTK_PRIVATE_CFLAGS "-DASMTK_STATIC")
endif()
```

--------------------------------

### AsmTK Target Type Determination

Source: https://github.com/asmjit/asmtk/blob/master/CMakeLists.txt

Determines the AsmTK target type (EMBED, STATIC, or SHARED) based on the configuration variables ASMTK_EMBED and ASMTK_STATIC. This sets the ASMTK_TARGET_TYPE variable accordingly.

```cmake
if (ASMTK_EMBED)
  set(ASMTK_TARGET_TYPE "EMBED")
elseif (ASMTK_STATIC)
  set(ASMTK_TARGET_TYPE "STATIC")
else()
  set(ASMTK_TARGET_TYPE "SHARED")
endif()
```
