Using https://github.com/qgis/QGIS/archive/master.zip and David Marteau's makefile at https://www.3liz.com/blog/rldhont/index.php?post/2017/06/01/How-to-build-qgis-on-OSX-with-MacPort and adding
-DLIBZIP_INCLUDE_DIR:PATH=/opt/local/include \ -DLIBZIP_CONF_INCLUDE_DIR:FILEPATH=/opt/local/lib/libzip/include \ -DLIBZIP_LIBRARY:FILEPATH=/opt/local/lib/libzip.dylib \
I'm able to build QGIS2.99 to this point:
In file included from /Users/liontooth/software/QGIS/QGIS-2.99a/tests/src/providers/testqgspostgresprovider.cpp:4: In file included from /Users/liontooth/software/QGIS/QGIS-2.99a/src/providers/postgres/qgspostgresprovider.h:24: /Users/liontooth/software/QGIS/QGIS-2.99a/src/providers/postgres/qgspostgresconn.h:33:10: fatal error: 'libpq-fe.h' file not found
The file is /opt/local/include/postgresql96/libpq-fe.h, supplied by MacPort postgresql96. How do we tell the build process where to find it?
I tried adding paths to the makefile, which worked fine with libzip, and modifying cmake/FindPostgres.cmake directly, but no dice.

Assuming that the Postgresql95 (or 96, but I'm still using 95 atm) port is installed, the cmake configure locate the postgres library:
-- Found PostgreSQL: /opt/local/lib/postgresql95/libpq.dylib
CMake use pg_config to locate the posgres library and includes, check that the CMakeCache.txt created in the build directory contains the following (should be quite similar with postgres96):
//Path to POSTGRESQL base directory POSTGRESQL_PREFIX:PATH= POSTGRES_CONFIG:FILEPATH=/opt/local/bin/pg_config POSTGRES_CONFIG_PREFER_PATH:STRING=/bin POSTGRES_INCLUDE_DIR:STRING=/opt/local/include/postgresql95 POSTGRES_LIBRARY:STRING=/opt/local/lib/postgresql95/libpq.dylib //Determines whether POSTGRESQL support should be built WITH_POSTGRESQL:BOOL=TRUE
There is also some cases where include paths are not reported to the CMakeLists.txt of some modules (see https://github.com/qgis/QGIS/pull/5196).
It seems that the compilation fail on compiling test, did the compilation succeeded when building the provider module itself ?
