CMakeLists.txt:9 (find_package)

========================================================================

Found the reason.
My git is not on C drive,I changed the git path to C drive.

FindBash.cmake file in the ktx package.
FindBash.cmake

First, look if GIT bash is installed

find_program (
BASH_EXECUTABLE
bash
PATHS
# Additional paths for Windows
“C:\Program Files\Git\bin”
NO_SYSTEM_ENVIRONMENT_PATH
)

if(NOT BASH_EXECUTABLE)

Fallback search in default locations

WSL bash did not work in my case :frowning:

find_program (
BASH_EXECUTABLE
bash
)
endif()

KTX requires bash. If WSL bash doesn’t work, please try installing Git for Windows, which includes Bash.

I have git， but it still doesn’t work.
I’ve seen you in the topic of vcpkg error for more than one time, every way you provide has been proved doesn’t work and every mistake you mentioned i had never made, But I still meet this problem.

6

Not only ktx has error. When I first built it was draco and this time it was ktx. I skipped ktx but it still appears the same problem in openssl. More than one dependencies has met this problem when building by ezvcpkg.
