Qt5GLib-2.0 development package not found

[rtvideo]

I have all of these packages sudo installed onto my ubuntu machine but for some reason I still am getting errors for almost all of them saying the package cannot be found. Do I have to move them into the project folder or link them using the paths somehow?

CONFIG += link_pkgconfig

# QMAKE_CXXFLAGS += -DQT_GUI_LIB -DQT_CORE_LIB -D_REENTRANT

TEMPLATE = app

unix:!macx {
    PKGCONFIG += Qt5GLib-2.0

Hi,

Are you sure the casing is correct ?
Did you install the development package of these libraries installed ?
If your run pkg-config on the command line, can you get the information about these packages ?

When I run pkg-config and then the package name nothing will come up for them

[SGaist]

Then Qt won't do miracle for that. Do you have any .pc files for these libraries ?

Figured it out from your comment, I had the package itself but not the development one, installing that I believe fixed it
