[Interest] Solution to Qt 5.5.1 build fails on win7 in qt3d with fatal error C1083: Cannot open include file: 'zlib.h': No such file or directory

[Gunnar Roth]

Hello,
reply to myself to tell about the found solution.
I am doing a shadow build of qt, this fails. 
So does the Qt Ci not making shadow builds? 
 
I looked into qtsvg\src\svg\svg.pro
And saw:
contains(QT_CONFIG, system-zlib) {
    if(unix|mingw):          LIBS_PRIVATE += -lz
    else:                    LIBS += zdll.lib
} else {
    git_build: \
        INCLUDEPATH += $$[QT_INSTALL_HEADERS/get]/QtZlib
    else: \
        INCLUDEPATH += $$[QT_INSTALL_HEADERS/src]/QtZlib }

While qt3d\src\3rdparty\assimp\assimp.pri
Has:
contains(QT_CONFIG, system-zlib) {
    unix|mingw: LIBS += -lz
    else: LIBS += zdll.lib
} else {
    INCLUDEPATH += $$[QT_INSTALL_HEADERS/get]/QtZlib }


So I replaced the fragment in assimp.pri by the one from svg.pro.


Et Voila, it works now.

Gunnar Roth
