Build fails if sdbus-cpp 1.2.0 headers are installed.

[cgevans]

It appears that, if sdbus-cpp is not installed, then 1.4.0 will be built. If 1.4.0 is system-installed, then the build will also work. However, if an earlier version (eg, 1.2.0 is the latest version in Fedora 39) is installed, the build will fail (see below). The version of sdbus-cpp should probably be checked, if it is found.

I fixed the problem with just adding the header file
#include <condition_variable> at the recommended place.

however after these packages compiled :

Yes, I should have clarified: the error message I pasted there is just the first error that shows up, a symptom of needing sdbus-cpp 1.4.0, not 1.2.0. Fixing that symptom just results in another error. The build process needs to be changed to depend on 1.4.0.
