If you override an already existing macro/command, the previous version is
still available, but with an underscore prefixed, i.e. _find_library().
I'm not sure I remember correctly, but it was somethign close to this.
You remembered correctly... It works. Thank's...
The only funny thing (another cmake mystery) is that it did not work as
a macro. This small program:
PROJECT(OpenMEEG)
CMAKE_MINIMUM_REQUIRED(VERSION 2.6 FATAL_ERROR)
MACRO(FIND_LIBRARY VAR)
MESSAGE("${VAR} ${ARGN}")
_FIND_LIBRARY(${VAR} ${ARGN})
ENDMACRO()
FIND_PACKAGE(PythonLibs)
fails with the message:
CMake Warning (dev) at CMakeLists.txt:6 (MESSAGE):

Policy CMP0010 is not set: Bad variable reference syntax is an
error. Run
"cmake --help-policy CMP0010" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.

This warning is for project developers. Use -Wno-dev to suppress it.
[.... more messages of the same vein .....]
while this one (with function instead of macro) works....
PROJECT(OpenMEEG)
CMAKE_MINIMUM_REQUIRED(VERSION 2.6 FATAL_ERROR)
FUNCTION(FIND_LIBRARY VAR)
MESSAGE("${VAR} ${ARGN}")
_FIND_LIBRARY(${VAR} ${ARGN})
ENDFUNCTION()
