# WRITE_BASIC_CONFIG_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion) )
|
||
|
|
#
|
||
|
|
# Writes a file for use as <package>ConfigVersion.cmake file to <filename>.
|
||
|
|
# See the documentation of FIND_PACKAGE() for details on this.
|
||
|
|
# filename is the output filename, it should be in the build tree.
|
||
|
|
# major.minor.patch is the version number of the project to be installed
|
||
|
|
# The COMPATIBILITY mode AnyNewerVersion means that the installed package version
|
||
|
|
# will be considered suitable if it is newer or exactly the same as the requested version.
|
||
|
|
# If SameMajorVersion is used instead, then the behaviour differs from AnyNewerVersion
|
||
|
|
# in that the major version number must be the same as requested, e.g. version 2.0 will
|
||
|
|
# not be considered suitable to 1.0 is requested.
|
||
|
|
# If you project has more elaborated version matching rules, you will need to write your
|
||
|
|
# own custom ConfigVersion.cmake file, instead of using this macro.
|
||
|
|
#
|
||
|
|
# Internally, this macro executes configure_file() on the input file
|
||
|
|
# Modules/BasicConfigVersion-AnyNewerVersion/SameMajorVersion.cmake.in to
|
||
|
|
# create the resulting version file.
