Brad,
I do not agree if multiple packages/find scripts come into play because
each client project has to take care of cmakes internal structure.
We use FIND_PACKAGE with <Package>Config.cmake for our *major* packages
and are happy with some possibly "interactive" or "-D" <Package>_DIR
settings.
However, our >70 additional "simple" find scripts do not belong to a
special package.
Just like the CMake/Modules scripts teh y look for some external
libs+headers.
They are used by many projects and canbe thought of as "installed",
belong to an independant cvs etc.
To use these additional find scripts
- without "complicated" -D setting on cmake call
- wrapping shell script etc...
we need something as ugly as this:
# environment variable should contain our additional cmake find script
Modules
SET(CMAKE_MODULE_PATH $ENV{CMAKE_MODULE_PATH})
IF(NOT CMAKE_MODULE_PATH)
MESSAGE(FATAL_ERROR "FATAL ERROR: Please set shell variable
CMAKE_MODULE_PATH to our additional CMakeModules repository.")
ELSE(NOT CMAKE_MODULE_PATH)
# a user modules path is set
# check for at least one of our find scripts to be sure the path is no
crap.
FIND_FILE(BIAS_CMAKE_MODULE_PATH_OK FindBLAS.cmake
${CMAKE_MODULE_PATH} DOC "testing CMAKE_MODULE_PATH")
IF (NOT BIAS_CMAKE_MODULE_PATH_OK)
MESSAGE(FATAL_ERROR "Your CMAKE_MODULE_PATH=${CMAKE_MODULE_PATH} is
invalid because FindBLAS.cmake not found. Please set shell variable
CMAKE_MODULE_PATH to your (cvs) CMakeModules repository.")
ENDIF (NOT BIAS_CMAKE_MODULE_PATH_OK)
ENDIF(NOT CMAKE_MODULE_PATH)
MARK_AS_ADVANCED(BIAS_CMAKE_MODULE_PATH_OK)
Extending cmake would be much easier and more "open"
with an easy way to extend teh search path for FIND_PACKAGE.
What do you think?
Jan.
