check_c_source_compiles(" #include <stdint.h> int main() { uintptr_t i; i = 12; return (int)i; }" HAVE_UINTPTR_T) 由5可以知道,包了CheckCSourceCompiles,可以直接对下面的小代码进行简短的编译,编译过了会设置 HAVE_UINTPTR_T为真,后面可以再进行打印以及处理。 if (HAVE_UINTPTR_T) mes...
CMake provides the try_compile() command and wrapper macros such as CheckCXXSourceCompiles, CheckCXXSymbolExists and CheckIncludeFile to test capability and availability of various toolchain features. These APIs test the toolchain in some way and cache the result so that the test does not have ...
