Hi Lloyd,
Personally I copy the DLLs to the VS folder (so that the program can be run
from visual studio) using the following script.
It looks more complicated than it is.
A macro is available to several of my projects to select which Qt module they
use and create a list of dlls to copy.
Then I simply choose where to copy the DLLs according to the generator.
I also add them to the list of files to install.
Finally the last line is to remove the command prompt opening.
MACRO(GetQtDLLs DEBUG_NAME RELEASE_NAME)
FOREACH(module QT3SUPPORT QTOPENGL QTASSISTANT QTDESIGNER QTMOTIF QTNSPLUGIN

set (DLL_TO_DBG ${CMAKE_CURRENT_BINARY_DIR}/Debug)
set (DLL_TO_RELEASE ${CMAKE_CURRENT_BINARY_DIR}/Release)
else()
# for other version of visual studio the DLLs are expected into

Subject: [CMake] Copy dlls to release and debug folder
Hi,
I was successful in creating and building a project using CMake on Windows
(Visual Studio). After the build when I try to run the application it throws an
error asking for the dlls of Qt (I know it is a common case in Windows, usually
we do copy the dlls to debug/release folder where the exe resides). When I
searched the mailing list, I have seen an advise to use
"add_custom_command(TARGET ...)". Is this the right approach? Wont it be
executed after each build, thus causing repeated dll copies?
Can you please suggest me the right way?
Thanks,
Lloyd
