QMAKE variable not work as expected

Adam BZH

I'm working on a project with Qt. I'm trying to separate app and lib in different folder by using customized pri files

But the QMAKE var TEMPLATE changes randomly for the same sub-project. Makes no sense for me.

part of downloader_tester.pro

include(../../build_path.pri)
TARGET = downloader_tester
TEMPLATE = app

part of build_path.pri

#envs
PREFIX = $${TOPDIR}/_build

CONFIG(release, debug|release):DEB_REL = _release
CONFIG(debug, debug|release):DEB_REL = _debug

INSTALL_DIR_BIN = $${PREFIX}/$${DEB_REL}/bin
INSTALL_DIR_LIBS = $${PREFIX}/$${DEB_REL}/libs

QMAKE_LIBDIR += $${INSTALL_DIR_LIBS}
INCLUDEPATH += $${TOPDIR}

win32:CMD_MKDIR = "md"
unix:CMD_MKDIR = "mkdir -p"

win32:CMD_DEL = "rm" #since I'm using msys2
unix:CMD_DEL = "rm"

if(eval(TEMPLATE = "app"))
{
    install_bin.files += $${OUT_PWD}/$${str_member($${DEB_REL},1,-1)}
    #install_libs.extra = $${CMD_DEL} *.o *.cpp *.h
    message("=================================")
    message(TARGET=$${TARGET})
    message(TEMPLATE=$${TEMPLATE})
    message(INSTALL_DIR_BIN=$${INSTALL_DIR_BIN})
    message(DESTDIR=$${DESTDIR})
    message("*********************************")
}

if(eval(TEMPLATE = "lib"))
{
    LIBS += -L$${OUT_PWD}/$${str_member($${DEB_REL},1,-1)} -l$${TARGET}
    message("=================================")
    message(TARGET=$${TARGET})
    message(TEMPLATE=$${TEMPLATE})

    message(DESTDIR=$${DESTDIR})
    message("*********************************")
    message($${OUT_PWD}/$${str_member($${DEB_REL},1,-1)})
}

SINGLE Time QMAKE

We can clearly see that TEMPLATE change from app to lib and change back few time for the SAME PROJECT. Even the release change to debug at the end.

What is happening...???

jsulm

@Adam-BZH Looks correct to me: for app it is storing binary in bin and for lib in lib. What is inside your pri files?

@jsulm I provided my pri file in op

Solved by make the { at the same line with equals....
There is no any warning or error from qmake, it just ignore that line but still exec the code inside that { }.
What the f is this, took me 5 hours to find it out.
