Matt,
you need to install the "libproj-dev" package.
Looking at the CI build recipees is a source of good hints in general:
https://github.com/OSGeo/gdal/blob/6e6aff451dbcde450f051bff2f2e75ce6a4a3e6f/.github/workflows/cmake_builds.yml#L38
(this one has pretty much all the pre packaged dependencies. you don't
need all that)

This what I've come up with:
https://gitpod.io
Create new >> search for gdal >> select OSGeo/gdal
On launch:
-- Could NOT find PROJ (missing: PROJ_DIR)
CMake Error at
/home/linuxbrew/.linuxbrew/Cellar/cmake/3.22.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230
(message):
Could NOT find PROJ (missing: PROJ_LIBRARY PROJ_INCLUDE_DIR) (Required is
at least version "6.0")
Call Stack (most recent call first):
/home/linuxbrew/.linuxbrew/Cellar/cmake/3.22.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:594
(_FPHSA_FAILURE_MESSAGE)
cmake/modules/packages/FindPROJ.cmake:57
(find_package_handle_standard_args)
cmake/helpers/CheckDependentLibraries.cmake:303 (find_package)
gdal.cmake:210 (include)
CMakeLists.txt:206 (include)
Attempted to remedy this with `sudo apt install proj-bin` but same
error from `cmake .`
----------------------------------------------------------------------------------
The below adapted from
https://github.com/maphew/gdal/blob/pr-5281-redux/CONTRIBUTING.md
cd /workspace/gdal
./autogen.sh
./configure --with-python
Fails with "configure: error: PROJ 6 symbols not found".
tried `sudo apt install proj-bin` and repeated above, same error.
Version of proj that's installed with this is 6.3.1.
Try building Proj from source (takes awhile):
cd /workspace
wget https://download.osgeo.org/proj/proj-6.3.1.tar.gz
<https://download.osgeo.org/proj/proj-6.3.1.tar.gz>
tar zxf proj-*.gz
cd proj-6.3.1
./configure
make && sudo make install
Now try again (takes much longer):
cd /workspace/gdal
./autogen.sh
./configure --with-python
make -j8
sudo make install
It works!

I'm still unable to successfully install a python wheel of gdal-utils,
because pip is calling g++ which in turn is not finding libgdal, but
it still feels like significant progress to get this far! :)
