In situations where included header have same name as their parent dir, i.e.
include/QtMyModule/QtMyModule and #include <QtMyModule> on code. moc will fail if parent dir was
added in front of includepath.
moc -Iinclude -Iinclude/QtMyModule fails
moc -Iinclude/QtMyModule works
This patch move dir test to proper place, as entry is validated only if is a real file, not a dir.
Detected by qca2 plugins code that uses QtCrypto/QtCrypto
Thanks to Thiago to find proper syntax
