hi,
currently, I know 3 different specifications, how FindXXX.cmake files
should look like:
- the shipped modules in /usr/share/cmake-2.4/Modules/
- the readme.txt in /usr/share/cmake-2.4/Modules/
- CMake_HowToFindInstalledSoftware.html in the wiki
unfortunately, these specifications are inconsistent! and the
sentence "We would like all FindXXX.cmake files to produce consistent
variable names." in the readme.txt is currently really ridiculous...
The readme is the way it is supposed to be. However, many of the
modules were created before the readme was created. Due to two
factors, backwards compatibility and a lack of time to make the Find*
stuff more consistent it is not. New modules should follow the
readme. If you have the time, you are welcome to update all of the
other modules to meet the specs. However, the old variables need to be
kept as well as the new ones that match the readme.txt so that we don't
break any existing projects. I will change the readme to note this
problem to avoid confusion in the future. At some point, I am sure it
will all be cleaned up, but unless someone steps up to the plate, there
are other more structural things that will be done in cmake first. The
individual models should be documented, and --help-module FindXXX will
give you the specifications of a specific module.
