Given the following manifest (when `dnn` feature is not included):
```json
"dependencies": [
{
"name": "opencv4",
"version>=": "4.8.0#18",
"default-features": false,
"features": [
"png"
]
}
]
```
it failed and here is what
`vcpkg/buildtrees/opencv4/config-x64-linux-out.log` said:
```
...
CMake Error at /home/peter/open-source/git/vcpkg/scripts/buildsystems/vcpkg.cmake:859 (_find_package):
Could not find a package configuration file provided by "flatbuffers" with
any of the following names:
flatbuffersConfig.cmake
flatbuffers-config.cmake
Add the installation prefix of "flatbuffers" to CMAKE_PREFIX_PATH or set
"flatbuffers_DIR" to a directory containing one of the above files. If
"flatbuffers" provides a separate development package or SDK, be sure it
has been installed.
Call Stack (most recent call first):
CMakeLists.txt:759 (find_package)
...
```
This problem is introduced by [commit
6d2c9714](6d2c971458)
contributed by @jimwang118
In the patch `vcpkg/ports/opencv4/0023-fix-no-flatbuffers.patch`, Jim
disabled the procedure of `Flatbuffers` detection introduced by the
previous patch `0017-fix-flatbuffers.patch`, which has correctly fixed
the `flatbuffers`-related issues.
```patch
...
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -756,7 +756,7 @@ include(cmake/OpenCVFindLibsVideo.cmake)
include(cmake/OpenCVFindLibsPerf.cmake)
include(cmake/OpenCVFindLAPACK.cmake)
include(cmake/OpenCVFindProtobuf.cmake)
-include(cmake/OpenCVDetectFlatbuffers.cmake)
+find_package(flatbuffers CONFIG REQUIRED)
...
```
In `vcpkg/ports/opencv4/vcpkg.json` we can see, `flatbuffers` is only
the dependency of feature `dnn`:
```json
"dependencies": [
...
"dnn": {
"description": "Enable dnn module",
"dependencies": [
"flatbuffers",
{
"name": "flatbuffers",
"host": true,
"default-features": false
},
"protobuf"
]
},
...
```
and when `dnn` is not enabled, it broke down at the line
`find_package(flatbuffers CONFIG REQUIRED)`
And this change is unnecessary either:
```patch
- list(APPEND libs ocv.3rdparty.flatbuffers)
+ list(APPEND libs flatbuffers::flatbuffers)
```
Thus, we'd better to revert those changes.
