Check once if C++ source code can be compiled.
|
|
|
|
Options:
|
|
|
|
CXXFLAGS - A list of additional flags to pass to the compiler.
|
|
|
|
LDFLAGS - A list of additional flags to pass to the linker.
|
|
|
|
LINK_LIBRARIES - A list of libraries to add to the link command.
|
|
|
|
For historical reasons, among the CMake `CMAKE_REQUIRED_*` variables that influence
|
|
`check_cxx_source_compiles()`, only `CMAKE_REQUIRED_FLAGS` is a string rather than
|
|
a list. Additionally, `target_compile_options()` also expects a list of options.
|
|
|
|
The `check_cxx_source_compiles_with_flags()` function handles this case and accepts
|
|
`CXXFLAGS` as a list, simplifying the code at the caller site.
