// Used when we need to compile with no source code

Implement a more direct headersclean check Test each include file directly, instead of doing a large #include. This verifies that each header is compilable on its own. One big advantage of doing it via a special compiler in qmake is that we skip pre-compiled headers, which has hidden build errors in the past. This solution is implemented by making syncqt produce a second list of headers. This list is the same as the list of headers in the source code to be installed, minus the headers that declare themselves to be unclean, via the pragma: #pragma qt_sync_skip_header_check This mechanism is applied only for public libraries (skipping QtPlatformSupport, an internal_module). This test is enabled only for -developer-builds of Qt because it increases the compilation time. On QtTest: the library only links to QtCore, but it has two headers that provide inline-only functionality by including QtGui and QtWidgets headers (namely, qtest_gui.h and qtest_widget.h). If those two modules aren't getting compiled due to -no-gui or -no-widgets to configure, we need to remove the respective headers from the list of headers to be checked. If they are being built, then we need to make QtTest's build wait for the headers to be generated and that happens when qmake is first run inside the src/gui and src/widgets directories.
