When building with the following command, and not removing the lib/cmake folder,

conan create . arrow/1.0.0@ -o arrow:parquet=True -o arrow:plasma=True -o arrow:gandiva=False

the following files in lib/cmake/arrow are created:

bc80bb8129066ff1ad369bc4dea6f097af21af89/lib/cmake/arrow/
├── arrow-config.cmake
├── ArrowConfig.cmake
├── ArrowConfigVersion.cmake

├── ParquetTargets.cmake
├── ParquetTargets-release.cmake

The following pkgconfig files are generated:

From the list above, Conan is able to generate:

arrow-compute.pc <-- (not now, but possible adding the component)
arrow.pc
parquet.pc
plasma.pc

FindArrow.cmake

ArrowConfigVersion.cmake
ArrowTarget-release.cmake  <-- (should it be ArrowTargets-release.cmake?? note the extra 's')
ArrowTargets.cmake
ArrowConfig.cmake

[madebr]

arrow-compute.pc <-- (not now, but possible adding the component)

arrow-compute.pc is just a wrapper around arrow.pc:

Name: Apache Arrow Compute
Description: Compute modules for Apache Arrow
Version: 1.0.0
Requires: arrow

ArrowTarget-release.cmake <-- (should it be ArrowTargets-release.cmake?? note the extra 's')

That doesn't matter.
This file is generated using install(EXPORT ... DESTINATION lib/cmake/arrow FILE ArrowTarget.cmake).

Is there a conan issue about adding support for multiple FindXXX.cmake files in the generators?
