 With QGIS 1.6.0, the CMake scripts seem to be unable to detect the GEOS or
 GRASS libraries even though they are accessible in /usr/local/lib.

 Running cmake .., I get:

 {{{
 GEOS_INCLUDE_DIR=/usr/local/include
 GEOS_LIBRARY=GEOS_LIBRARY-NOTFOUND
 CMake Error at cmake/FindGEOS.cmake:163 (MESSAGE):
   Could not find GEOS
 Call Stack (most recent call first):
   CMakeLists.txt:141 (FIND_PACKAGE)


 -- Configuring incomplete, errors occurred!
 }}}

 It is odd that CMake discovers the headers, but fails to find the library.

 Even stranger, is that if I add a tracing statement after line 135 of
 FindGEOS.cmake:

 {{{
 IF (APPLE)
   SET(GEOS_LIBRARY ${GEOS_LINK_DIRECTORIES}/lib${GEOS_LIB_NAME}.dylib
 CACHE STRING INTERNAL)
   MESSAGE("Library should be set to:
 ${GEOS_LINK_DIRECTORIES}/lib${GEOS_LIB_NAME}.dylib")
 ELSE (APPLE)
 }}}

 I see a message printed out that has the correct path to the library, yet
 GEOS_LIBRARY is still set to GEOS_LIBRARY-NOTFOUND.

 If I replace the call to SET with a call to FIND_LIBRARY, everything
 works:

 {{{
  IF (APPLE)
    FIND_LIBRARY(GEOS_LIBRARY ${GEOS_LIB_NAME}
      PATHS ${GEOS_LINK_DIRECTORIES}/lib)
  ELSE (APPLE)
 }}}

 Attached is a patch that makes this change for FindGEOS.cmake and
 FindGDAL.cmake.  I don't have William Kyngesburye's frameworks installed
 so I can't judge whether or not these changes negatively impact his build
 process.

 Version 1.5.0 builds from source just fine.
