Provides a macro to check if a header file can be included in C
.
CHECK_INCLUDE_FILE
CHECK_INCLUDE_FILE(<include> <variable> [<flags>])
Check if the given <include>
file may be included in a C
source file and store the result in an internal cache entry named <variable>
. The optional third argument may be used to add compilation flags to the check (or use CMAKE_REQUIRED_FLAGS
below).
The following variables may be set before calling this macro to modify the way the check is run:
CMAKE_REQUIRED_FLAGS
CMAKE_REQUIRED_DEFINITIONS
CMAKE_REQUIRED_INCLUDES
CMAKE_REQUIRED_LIBRARIES
CMP0075
.CMAKE_REQUIRED_QUIET
See the CheckIncludeFiles
module to check for multiple headers at once. See the CheckIncludeFileCXX
module to check for headers using the CXX
language.
