# Issue (Bug) xz binary is not found since PATH is not used for binary resolution anymore. Introduced on pull request github jnovy/pxz/pull/33. Renders default pxz build unfunctional. Probably introduced with security fix #881377. See github jnovy/pxz/issues/34 for a possible workaround (specifying -DXZ_BINARY="/usr/bin/xz" during make). ## Reproduction 1. Emerge app-arch/pxz-5.0_pre20220509 2. Run `pxz --help` or any other pxz command. ## Result ```text Parallel PXZ-4.999.9beta-20221219, by Jindrich Novy <...> Options: -g, --crc32 use CRC32 checksum method (default CRC64) -T, --threads maximum number of threads to run simultaneously -D, --context-size per-thread compression context size as a multiple of dictionary size. Default is 3. Usage and other options are same as in XZ: pxz: execution of xz binary failed: No such file or directory ``` ### Expected ```text Parallel PXZ-4.999.9beta-20221219, by Jindrich Novy <...> Options: -g, --crc32 use CRC32 checksum method (default CRC64) -T, --threads maximum number of threads to run simultaneously -D, --context-size per-thread compression context size as a multiple of dictionary size.

Thank you!
On reflection, later on I'll change it to pass the path to CMake with EPREFIX, but it'll be functionally the same.
