Can't find any -lQt5* libraries

rw3iss

Hiyas,

Trying to compile a project, and I get the following list of errors:

:-1: error: cannot find -lQt5Svg
:-1: error: cannot find -lQt5Gui
:-1: error: cannot find -lQt5Core
:-1: error: cannot find -lQt5Widgets
:-1: error: cannot find -lQt5Xml
:-1: error: cannot find -lQt5Network
:-1: error: cannot find -lQt5WebKitWidgets
:-1: error: cannot find -lQt5WebKit
:-1: error: cannot find -lQt5V8
:-1: error: cannot find -lQt5XmlPatterns
:-1: error: cannot find -lQt5PrintSupport
:-1: error: cannot find -lQt5Quick
:-1: error: cannot find -lQt5Qml
collect2.exe:-1: error: error: ld returned 1 exit status

I am on a Windows 64-bit PC, running Qt Creator 5.2. I am in debug mode, and am using the MinGW compiler.

My computer's PATH variable includes the Qt /bin directory:
C:\Qt\Tools\mingw48_32\bin;C:\Qt\Tools\mingw48_32\lib;C:\Qt\5.2.0\mingw48_32\bin;C:\Qt\Tools\QtCreator\bin;C:\Program Files (x86)\CMake 2.8\bin

And the C:\Qt\Tools\mingw48_32\bin includes such files as Qt5Cored.dll, Qt5Guid.dll, Qt5Svgd.dll, Qt5Xmld.dll, and I think all of the rest in the error list.

I'm running Cmake with the following arguments:
-DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_TOOLCHAIN_FILE=build/mingw32.mingw.cmake -DCMAKE_INSTALL_PREFIX=../win32install

And here is the output for 'Run Cmake':

Disabling ALSA support due to OS X or MINGW build.

I also tried adding 'QT += core' to the mscore.pro file, which is contained in a directory 'build.qtc' underneath the main source directory. I don't know if this .pro file is even being used. How can I tell?

Why can't it find the Qt libraries?

Does anyone have ANY idea how to solve this?
Would be much appreciated.
