Thank you for your response Andreas,

Actually I get a not so cryptic error, which says that it does not find the
module:

 CMake Warning at CMakeLists.txt:12 (find_package):
  Could not find module Findmylib.cmake or a configuration file for package
  mylib.

  Adjust CMAKE_MODULE_PATH to find Findmylib.cmake or set mylib_DIR to the
  directory containing a CMake configuration file for mylib.  The file will
  have one of the following names:

    mylibConfig.cmake
    mylib-config.cmake


So, to my understanding, cmake will search the module at CMAKE_MODULE_PATH
or at /usr/share/cmake-2.6/Modules/
Does it also search somewhere else such as:
/usr/local/share/cmake-2.6/Modules ?
I've tried this and apparently it doesn't search there... (maybe it searches
somewhere
else?)
If cmake does not do this at all... would this be useful? I think so,
personally... since
usually it is common to install libraries/programs at /usr/local/...
