[REG 5.13->5.14] can't find SOURCES with wildcards and absolute paths

Steps to reproduce:

int main() {}

Put the above into test.cpp

SOURCES = $$PWD/*.cpp

And put the above into test.pro and run qmake test.pro

Qt 5.13.2 has no problem, while Qt 5.14.0 emits the following:

WARNING: Failure to find: D:/Mat/Projects/test/*.cpp

and the generated makefile is broken, as it contains references to the path with unexpanded wildcard, rather than the file path that the wildcard should have matched.

I also get the same problem with HEADERS, and with extra compilers too.
