add the installation prefix of "pplcv" to CMAKE_PREFIX_PATH or set "pplcv_DIR" to a directory containing one of the above files. If "pplcv" provides a separate development package or SDK, be sure it has been installed.

Did you set pplcv_DIR before find_package?

@ouonline echo ${PPLCV_DIR} ， The path output is correct

@ouonline echo ${PPLCV_DIR} ， The path output is correct

set pplcv_DIR in CMakeLists.txt:

set(pplcv_DIR /path/to/install/lib/cmake/ppl)

not the bash environment.
