I am trying to run a Flutter application with flutter_secure_storage as a dependency on linux. This dependency in turn needs libsecret and won't compile despite the path being present in LD_LIBRARY_PATH:

Content of $LD_LIBRARY_PATH:
/nix/store/8qdl40qaqck04bha609c1jhkqsihm4l2-vulkan-loader-1.3.283.0/lib:/nix/store/a5vcvrkh1c2ng5kr584g3zw3991vnhks-libGL-1.7.0/lib:/nix/store/ggzid0gk0j02d0549kscb3rr6yp0ma5a-libsecret-0.21.4/lib
How can I fix this and make flutter/cmake detect libsecret?
The fix was as per @Tsyvarev comment to rather use the CMAKE_PREFIX_PATH variable. Also, I added the pkg-config, libsecret.dev and gtk3.dev dependency. The CMAKE_PREFIX_PATH is set for the libsecret and gtk3 lib paths.
In addition as per https://github.com/NixOS/nixpkgs/issues/24215#issuecomment-1065924731 I removed said if statement and now it works :)
