Hello My Friend
I don't know how did you manage your CMakeLists.txt file and your build
system, so it should be related to many things, from Visual Studio version,
to debug and release versions of your build ... but specifically about
building Qt5 related UIs with *.mll *plugins of maya ( I did it
experimentally years ago) and for finding Qt related cmake config, you
should be able to build your tool successfully if you have these:
- In your CmakeLists.txt you should have these settings
include($ENV{DEVKIT_LOCATION}/cmake/pluginEntry.cmake)
$ENV{DEVKIT_LOCATION}: is my Env Variable of the Maya SDKS root location
You should enable these settings for Qt:
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)
After adding your Source files and Maya Libraries
# set SOURCE_FILES
set(SOURCE_FILES
myPlugin.cpp
main.cpp
)
# set linking libraries
set(LIBRARIES
OpenMaya
Foundation
)
You should add codes like this:
# Build plugin
build_plugin() # this will be find in maya sdk cmake config file
find_package(Qt5 COMPONENTS Core Widgets Gui OpenGL REQUIRED)
target_link_libraries($ENV{TARGET_NAME} Qt5::Core Qt5::Widgets Qt5::Gui
Qt5::OpenGL)
$ENV{TARGET_NAME}: you can set TARGET_NAME or PROJECT_NAME as your plugin
name
- I recommend to build your project through cmake with:
cd build
cmake -G "Visual Studio 17 2022" -A x64 ..
- It seems you are using GL/gl.h that I'm not sure it is related to Maya or
QT, but for OpenGL try to add this line to your CMakeLists.txt too
find_package(OpenGL REQUIRED)
Then open .sln file inside Visual Studio and build it in Debug and release
mode and see the difference!
I hope it helps you, if you have more Questions, please provide more data
like your CMakeLists.txt or build.bat file We can help more
