Same version here.

It looks like find_package looks first for FindFLEX.cmake in
/opt/local/share/apps/cmake/modules/, before
/opt/local/share/cmake-2.8/modules (note that, from the stack trace,
it looks like the kde version is in
/opt/local/share/apps/cmake/modules/, not in
/opt/local/share/cmake/modules).

On my linux, I also have two FindFLEX.cmake files, one from cmake (in
/usr/share/cmake-2.8/modules) and one from kdelibs (in
/usr/share/apps/cmake/modules/), but the right one is detected.

When I print the value of CMAKE_MODULE_PATH (before the calls to the
macro MACRO_OPTIONAL_FIND_PACKAGE), /usr/share/apps/cmake/modules/ is
listed (last position), but /usr/share/cmake-2.8/modules isn't. What
is the value of your CMAKE_MODULE_PATH?
