Is it possible to use the libproj macros? https://github.com/OSGeo/PROJ/blob/35e4207a9d9eb86b4e5188f00eae1f152306dad3/src/proj.h#L175-L177
or
https://github.com/OSGeo/PROJ/blob/35e4207a9d9eb86b4e5188f00eae1f152306dad3/src/proj.h#L188
eg.
#if PROJ_AT_LEAST_VERSION(<ubuntu 18.04 version>)
EXPECT_FLOAT_EQ(293.51068, dem.GetWorldHeight());
EXPECT_FLOAT_EQ(293.51089, dem.GetWorldWidth());
#else

I did try that initially (82b92ca), but the CI was complaining that it couldn't find "proj.h". Worked for me locally though.

I believe that will be resolved if you add find_package(PROJ REQUIRED) then add ${PROJ_INCLUDE_DIRS} to include_directories, and ${PROJ_LIBRARIES} to target_link_libraries
eg.,
Update:
gazebo-classic/gazebo/common/CMakeLists.txt
Lines 16 to 18 in 09fb1bc
To be:
if (HAVE_GDAL)
include_directories(${GDAL_INCLUDE_DIR})
if (PROJ_FOUND)
include_directories(${PROJ_INCLUDE_DIRS})
endif()
endif()I'm not sure what version of PROJ is being used but it may need PROJ4 instead: https://github.com/OSGeo/PROJ/blob/65f60f6e27482920aa5007af5357d1f37b220b90/cmake/CMakeLists.txt#L51-L56
