No libfreenect.pc installation on Mac OS X

[mindrones]

In short: when compiling on Mac OS X (10.7.5) libfreenect.pc is not installed, causing problems compiling other libraries depending on libfreenect.

---

In src/CMakeLists.txt this block:

IF(UNIX AND NOT APPLE)
  # Produce a pkg-config file for linking against the shared lib
  configure_file ("libfreenect.pc.in" "libfreenect.pc" @ONLY)
  install (FILES "${CMAKE_CURRENT_BINARY_DIR}/libfreenect.pc"
    DESTINATION "${PROJECT_LIBRARY_INSTALL_DIR}/pkgconfig")
ENDIF()`

prevents from installing libfreenect.pc. When compiling another library depending on libfreenect, this line in the offended library configure.ac:

PKG_CHECK_MODULES(FREENECT, libfreenect >= 0.0)

fails to find the libfreenect version causing compiling problems.

If there isn't a specific reason why this has been disabled, it would be nice to have it enabled.
