Unknown module(s) in QT: core gui concurrent

[Melu]

Hello I am getting the above error stating that the above modules are not known. I have recently reinstalled Qt on macos. During installation I selected the following:
.

After installation, I did the following to install the mysql library:

• cd ~/Qt5.12.10/5.12.10/Src/qtbase
• ./configure -opensource -confirm-license -plugin-sql-mysql MYSQL_PREFIX=/usr/local/mysql
• cd src/plugins/sqldrivers/
• qmake -- MYSQL_PREFIX=/usr/local/mysql
• make sub-mysql
• cd mysql
• make install

However when compiling my projects I am getting the error stating:

Project ERROR: Unknown module(s) in QT: core gui concurrent

I am not sure what I am missing from the installation stage as this has always worked for me. Any help would be much appreciated.

Thanks in advance.

What version of qmake is being run to build your projects?

qmake -v

You need to spell the modules in your CMakeLists.txt with a capital letter in the beginning.
Should be something like that:

find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Gui REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Core REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Concurrent REQUIRED)
