cps-config returns no cflags and wrong link flags

[madebr]

The script at the bottom of this post creates a dummy prefix looking as:

/tmp/dummyprefix
├── include
│   └── Futuro3
│       ├── Futuro.h
│       └── Futuro_test.h
└── lib
    ├── cps
    │   └── Futuro3.cps
    ├── libFuturo3.a
    ├── libFuturo3.so -> libFuturo3.so.0.1.2
    ├── libFuturo3.so.0 -> libFuturo3.so.0.1.2
    ├── libFuturo3.so.0.1.2
    └── libFuturo3_test.a

Actual output:

+ cps-config flags --cflags Futuro3

+ cps-config flags --libs Futuro3
-l/tmp/dummyprefix/lib/libFuturo3.so.0.1.2

Expected output:

+ cps-config flags --cflags Futuro3
-I/tmp/dummyprefix/include
+ cps-config flags --libs Futuro3
/tmp/dummyprefix/lib/libFuturo3.so.0.1.2

Script to create a dummy project:

#!/bin/sh

set -ex

cd /tmp
rm -rf dummyprefix
mkdir -p dummyprefix/lib/cps
mkdir -p dummyprefix/include/Futuro3
touch  dummyprefix/include/Futuro3/Futuro.h
touch dummyprefix/include/Futuro3/Futuro_test.h
touch dummyprefix/lib/libFuturo3.so.0.1.2
ln -s -r dummyprefix/lib/libFuturo3.so.0.1.2 dummyprefix/lib/libFuturo3.so.0 
ln -s -r dummyprefix/lib/libFuturo3.so.0 dummyprefix/lib/libFuturo3.so
touch dummyprefix/lib/libFuturo3.a
touch dummyprefix/lib/libFuturo3_test.a
