New description:

 When the CMake pgs are in use, add Boost to the module path. Something
 like this, which was recently added to port `cadabra2`:

 {{{
 # Ensure CMake can find the selected boost port
 # TODO: Do this automatically via Boost portgroup
 cmake.module_path-append \
                     [boost::lib_dir]/cmake
 }}}

 Original description:

 I'm not really sure if this is a cmake issue or a boost issue. I'm trying
 to build a non-macports app (OpenModelica) using cmake, and worked fine
 until recently. When I run cmake I now get these errors:

 {{{
 CMake Error at
 /opt/local/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:233
 (message):
   Could NOT find Boost (missing: Boost_INCLUDE_DIR program_options
   filesystem)
 Call Stack (most recent call first):
 /opt/local/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:603
 (_FPHSA_FAILURE_MESSAGE)
   /opt/local/share/cmake-3.31/Modules/FindBoost.cmake:2409
 (find_package_handle_standard_args)
 }}}

 I see this ticket that is having the same problem: #71642 Which suggests
 that it's a boost issue, but then has a fix of the cadabra2 port, where
 the problem was showing up.

 I do have boost176 and boost181 ports installed. I hadn't installed either
 directly, so they are dependents of other ports. I'm not familiar enough
 with Boost to understand how to make cmake "find" it.
