[CMake] Out-of-source build and access to data

[David Cole]

Send some code for us to look at.

If the cwd is where your exe is, and there's a file at "./data/file1"
then you should certainly be able to open and read that file with that
file name.

Maybe your cwd is not what you think it is.
Maybe your code changes it somewhere between launching and attempting
to open the file.

I don't understand where you're using a
filepath = "./data/file1"
reference? In your source code? In a settings file of some sort?
Certainly not in a CMakeLists.txt file since this is not cmake
syntax...
