Merge pull request #4533: BUILD(cmake): Fix use of generator expression

The changed files used a generator expression in an if-statement, which
is invalid as these generator expressions are not evaluated during the
initial configuration stage (at which point the if-statement is
evaluated).

This commit changes the use of the generator-expression in such a way
that it will actually do what it was meant to.

Note that this commit also enables position independent code for all
platforms and all build-types instead of only for debug builds on unix
systems. This was the preferred choice instead of porting the -fPIE
compiler option to use proper generator expressions as the presence of
these options caused linking errors with Celt/Opus.
