Program depends on build folder after install

[drkvogel]

Describe the bug
I built Sneedacity on my Ubuntu Studio system as per the instructions. It runs fine, but after I deleted the build folder in order to free up some disk space, I got an error:

To Reproduce
Steps to reproduce the behavior:

❯ mkdir build && cd build
❯ cmake -G "Unix Makefiles" -Dsneedacity_use_ffmpeg=loaded -DCMAKE_BUILD_TYPE=Release ..

(".." instead of "../sneedacity", which didn't work as there's no such directory, we're in sneedacity/build)

❯ make -j`nproc`
❯ sudo make install
❯ which sneedacity
/usr/local/bin/sneedacity
❯ sneedacity

OK, it runs, no complaints, but:

❯ cd ..
❯ mv build tmp
❯ sneedacity 
sneedacity: error while loading shared libraries: libwx_baseu_xml-3.1.so: cannot open shared object file: No such file or directory

Expected behavior
I expected the program to run after install without needing the build folder

Screenshots
If applicable, add screenshots to help explain your problem.

Additional information (please complete the following information):

• OS: Ubuntu Studio 20.04
• Version: Sneedacity 3.0.4-alpha-20220117

I've forgotten all the specifics but I recall there being an issue plaguing me forever where it wouldnt copy the libwx stuff to the destination/install directory which would cause all the tests to fail as well. at some point there was even a script somewhere after the install script that'd just copy those over. I'm (fairly) sure thats no longer how it works now but a good start would be to see if it just misses those libs when you look at the generated install target, unfortunately I'd have no clue where to start in trying to fix this issue. to confirm this is that: - confirm libwx_baseu_xml-3.1.so is linking to the build dir `ldd $(which sneedacity) | grep libwx_baseu` - check the generated install target to see if it hardcodes a list of stuff to copy over, instead of everything in the final destination directory I will look at it myself maybe possibly this weekend if you or no one else doesnt, should be findable

Yes, libwx_baseu_xml-3.1.so is linking to the build dir:

❯ ldd $(which sneedacity) | grep libwx_baseu 
	libwx_baseu_net-3.1.so => /usr/local/lib/sneedacity/libwx_baseu_net-3.1.so (0x00007f33c3649000)
	libwx_baseu-3.1.so => /usr/local/lib/sneedacity/libwx_baseu-3.1.so (0x00007f33c293e000)
	libwx_baseu_xml-3.1.so => /home/kvogel/p/sneedacity/build/bin/Release//lib/sneedacity/libwx_baseu_xml-3.1.so (0x00007f33c1c24000)

slowed by not being able to build it anymore with uptodate ffmpeg: #281
