# - Check if the include file exists.

# CHECK_INCLUDE_FILE_CXX(INCLUDE VARIABLE)
|
|
#
|
|
# INCLUDE - name of include file
|
|
# VARIABLE - variable to return result
|
|

|
|
# An optional third argument is the CFlags to add to the compile line
|
|
# or you can use CMAKE_REQUIRED_FLAGS.
|
|
#
|
|
# The following variables may be set before calling this macro to
|
|
# modify the way the check is run:
|
|
#
|
|
# CMAKE_REQUIRED_FLAGS = string of compile command line flags
|
|
# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
|
|
# CMAKE_REQUIRED_INCLUDES = list of include directories
