我想使用IAR编译器.我注意到CMake已经有一堆关于这个编译器的文件:

https://github.com/jevinskie/cmake/blob/master/Modules/Compiler/IAR.cmake

从我读到的常见解决方案是手动指定我的所有工具链CMakeLists.txt:

set(CMAKE_C_COMPILER iccarm)
set(CMAKE_CPP_COMPILER iccarm)

CMake如何将这些定义与`Modules/Compiler/IAR.cmake"联系起来？

我以为我只需要这样做

include("Modules/Compiler/IAR.cmake")

指定IAR编译器的正确方法是什么？

当我做

cmake .

它仍然试图使用gcc而不是我的IAR编译器.为什么？

我有一个 cmake 交叉编译器工具链文件，缩写为：

set(CMAKE_SYSTEM_NAME Linux)
if( DEFINED TC_PATH )
    message( STATUS " TC_PATH IS defined. ${TC_PATH}" )
else()
    message( FATAL_ERROR " TC_PATH not defined." )
endif()

set(CMAKE_C_COMPILER ${TC_PATH}/usr/bin/i586-linux/i586-linux-gcc )
set(CMAKE_CXX_COMPILER ${TC_PATH}/usr/bin/i586-linux/i586-linux-g++ )
set(CMAKE_LINKER ${TC_PATH}/usr/bin/i586-linux/i586-linux-ld )

我调用 cmake，设置 TC_PATH 以及工具链文件：

~/CMakeTest/output $ cmake -DTC_PATH:PATH=/opt/toolchain -DCMAKE_TOOLCHAIN_FILE=../toolchain.cmake ../

看来 cmake 正在多次调用工具链文件。在前两次，TC_PATH 检查成功，但后来，在识别编译器后，它抛出错误：

--  TC_PATH IS defined. /opt/toolchain
--  TC_PATH IS defined. /opt/toolchain
-- The C compiler identification is GNU 4.9.1
-- The CXX compiler identification is GNU 4.9.1
-- Check for working C …

我有这个CMakeLists.txt文件的问题:

cmake_minimum_required(VERSION 2.6)

SET(CMAKE_C_COMPILER C:\\MinGW\\bin\\gcc)
SET(CMAKE_CXX_COMPILER C:\\MinGW\\bin\\g++)

project(cmake_test)

add_executable(a.exe test.cpp)

用以下方式调用cmake: cmake -G "MinGW Makefiles"

我明白了:

c:\cmake_test>cmake -G "MinGW Makefiles" .
-- The C compiler identification is GNU 4.6.1
