[CLN-list] CMakeLists.txt: Improving GiNaC/CLN (& ease of) integration?

You could try https://github.com/asheplyakov/cln/tree/cmake
In order to compile both CLN and GiNaC just put cln sources into
ginac directory, and run CMake build. For instance

git clone git://www.ginac.de/ginac.git
cd ginac
git clone -b cmake git://github.com/asheplyakov/cln.git
mkdir _build
cd _build
cmake ..
cmake --build .

This will build both CLN and GiNaC

Similarly one can include both GiNaC and CLN sources into  another project,
and basically add_subdirectory(ginac)

Here is a complete example: https://www.ginac.de/git/?p=ginac.git;a=blob_plain;f=doc/examples/CMakeLists.txt;hb=c1083aea35fbc2c75baeec1286818f9c73a1f037

I use CMake to build both CLN and GiNaC

As far as I understand there's no technical reasons.

I think it's better to reuse the existing one.
