with lot of hackery, use add_executable on pascal files, SUCCSS

# Constraints:  GNAT_EXECUTABLE_BUILDER = gnatmake
# is required to do the compile+bind+link of
# Ada executables, and it requires a source file name which is constructed from
# <TARGET>.adb.  The source file arguments of add_executable are
# all compiled by the above rule (which must remain that form since it
# is also used to compile objects for Ada libraries), but the results are
# ignored since they are put in a different directory while gnatmake assumes
# objects are located in the _current_ directory.  Thus, put in a minimal
# source file (with correct .adb suffix to identify the Ada language)
# to reduce this useless compilation to a minimum.  Usually, the main Ada
# routine qualifies since it is normally small.  Thus, the normal usage is
# add_executable(foo foo.adb), but  add_executable(foo path/minimal.adb) would
# work as well so long as both path/minimal.adb existed and foo.adb existed.
# Also, note there is no way to specify
# ${CMAKE_CURRENT_SOURCE_DIR}/<TARGET>.adb as the code for gnatmake to compile
# because in this context ${CMAKE_CURRENT_SOURCE_DIR} is set to the top
# of the source tree and not the expected sub-directory of the source tree.
# Thus, LINK_FLAGS -aI${CMAKE_CURRENT_SOURCE_DIR} must be set using
# set_target_properties in order to specify the directory where <TARGET>.adb
# exists. Note, LINK_FLAGS can also be used to set other gnatmake flags
# such as -aL.

# In sum, you have to be careful of your target name, the nominal source file
# name has to be compilable, but otherwise it is ignored, and you must specify
# the required -aI and other GNAT_EXECUTABLE_BUILDER = gnatmake options
# using LINK_FLAGS specified with set_target_properties.
# However, so long as you pay attention to these
# constraints, add_executable should work for the Ada language.
