Latest Visual Studio 2026 with cmake 4 breaks my cmake install script

In older builds of VS 2026 Insiders the below install lines in CMakeLists.txt worked, I think the version of cmake was still v3.xx at that time. But I have just installed the newly released stable edtion of VS 2026 with cmake 4.1.1 and the install commands below no longer work

# Install the executable into bin/
install(TARGETS ${PROJECTNAME} RUNTIME DESTINATION bin)

# Install the fonts folder into bin/
install(
DIRECTORY ${CMAKESOURCEDIR}/fonts
DESTINATION bin
)


I get these errors (when I select Install from VS menu):

[0/1] Install the project...
-- Install configuration: "Debug"
CMake Error at cmakeinstall.cmake:41 (file):
file cannot create directory: C:/Program Files
(x86)/imgui-sfml-cmake-4300-2/bin. Maybe need administrative privileges.

ninja: build stopped: subcommand failed.

Has the syntax changed for the cmake install function? Why is it trying to install in C:/Program Files? In cmake 3.xx it would install into <project\name>\\out\\install\\x64-Debug\\bin.
