 The new mapserver component hardwires CMAKE_INSTALL_PREFIX in the
 executable.  This locks down the user install location of Qgis, which on
 OS X (maybe Windows also?) can change from the compiled
 CMAKE_INSTALL_PREFIX.

 But, I realize it could be tricky with the mapserv executable, since I
 think it wants the QGIS install path to be able to find Qgis resources.

 A couple similar options I can think of:

 - how the help app handles this: for the OS X build, it backtracks from
 prefixPath() to the Qgis executable (mapserv could use known
 QGIS_CGIBIN_SUBDIR values for different systems), then goes from there
 with the relative QGIS_*_SUBDIR vars.  Still a bit fragile, if the
 QGIS_CGIBIN_SUBDIR is configured different from default.

 - configure a matching QGIS_CGIBIN_SUBDIR_REV that backtracks (I use this
 in the OS X Xcode project in QGIS_LIBEXEC_SUBDIR_REV for other
 executables).  So, mapserv prefixPath() + "/" + QGIS_CGIBIN_SUBDIR_REV =
 Qgis prefixPath().  I don't know if the relative subdir vars are meant to
 be user-configurable, if so, this could be tricky to generate an inverse
 subdir during cmake configuration.

 ie, if QGIS_CGIBIN_SUBDIR = bin (unix, Mac), QGIS_CGIBIN_SUBDIR_REV = ..
