CMake QT_INSTALL_BIN_DIR not set to the value of CMAKE_INSTALL_BINDIR as expected

Perdrix

My CMakeLists.txt starts like this:

set(PROJECT_NAME DeepSkyStacker)

set(COMPILE_WARNING_AS_ERROR YES)
set(CMAKE_INSTALL_BINDIR ".")

find_package(Qt6 6.8 REQUIRED COMPONENTS Core Gui Widgets Network Charts LinguistTools)
qt_standard_project_setup()

Later on I have:

message ("Qt Deploy Bin Dir: " ${QT_DEPLOY_BIN_DIR})
message ("Target filename:"  $<TARGET_FILE_NAME:DeepSkyStacker>)
set(executable_path "\${QT_DEPLOY_BIN_DIR}/$<TARGET_FILE_NAME:DeepSkyStacker>")
message ("executable_path: " ${executable_path})
 qt_generate_deploy_script(
     TARGET DeepSkyStacker
     OUTPUT_SCRIPT deploy_script
     CONTENT "
 qt_deploy_runtime_dependencies(
     EXECUTABLE \"${executable_path}\"
     GENERATE_QT_CONF
     VERBOSE
 )")

The generate step produces output:

1> [CMake] System Name is: Windows prefix path: C:/Qt/6.8.0/msvc2022_64
1> [CMake] x64 architecture in use
1> [CMake] Install prefix set to: C:/Users/amonra/Documents/GitHub/DSS/x64/Debug
1> [CMake] -- Could NOT find WrapVulkanHeaders (missing: Vulkan_INCLUDE_DIR) 
1> [CMake] -- Could NOT find WrapVulkanHeaders (missing: Vulkan_INCLUDE_DIR) 
1> [CMake] -- Could NOT find WrapVulkanHeaders (missing: Vulkan_INCLUDE_DIR)

1> [CMake] Target filename:$<TARGET_FILE_NAME:DeepSkyStacker>
1> [CMake] executable_path: ${QT_DEPLOY_BIN_DIR}/$<TARGET_FILE_NAME:DeepSkyStacker>

Note that QT_INSTALL_BIN_DIR is empty, NOT the character .

The result is that the install fails:

which isn't surprising because it was looking for /DeepSkyStacker.exe, when it should have been looking for ./DeepSkyStacker.exe

So why was QT_INSTALL_BIN_DIR not set to the value of CMAKE_INSTALL_BINDIR?

@Perdrix said in CMake QT_INSTALL_BIN_DIR not set to the value of CMAKE_INSTALL_BINDIR as expected:

set(executable_path "${QT_DEPLOY_BIN_DIR}/$<TARGET_FILE_NAME:DeepSkyStacker>")

Why is there \ in front of ${QT_DEPLOY_BIN_DIR}?

Hmm - good question but it was there until a few moments back and removing it didn't change the behaviour. This thread now superseded, please see:
