Bug: Build error ISO C99 and later do not support implicit function declarations

[armanTabib]

Describe the bug
I have cloned the assimp project and I'm trying to build it for android. I go based on the assimp-doc project and when building I get following errors:

assimp/contrib/unzip/ioapi.c:114:16: error: call to undeclared function 'fopen64'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
...
/assimp/contrib/unzip/ioapi.c:114:14: error: incompatible integer to pointer conversion assigning to 'FILE *' (aka 'struct __sFILE *') from 'int' [-Wint-conversion]
...
/assimp/contrib/unzip/ioapi.c:144:21: error: call to undeclared function 'ftello64'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

...
/assimp/contrib/unzip/ioapi.c:190:8: error: call to undeclared function 'fseeko64'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

To Reproduce
Steps to reproduce the behavior:

1. clone the assimp project
2. run this command:
   cmake CMakeLists.txt -DASSIMP_ANDROID_JNIIOSYSTEM=ON -DCMAKE_TOOLCHAIN_FILE=path/to/sdk/ndk/27.0.11718014/build/cmake/android.toolchain.cmake -B ~/MyProjects/assimp-android/
3. Go to ~/MyProjects/assimp-android/
4. run cmake --build .
5. See the error

Edit :
I even edited the CMakeList.txt file like:
set(CMAKE_C_STANDARD 90).
But the error still exists.
Expected behavior
The project should build without error.

Platform (please complete the following information):

• OS: Ubuntu 23.04
• ndk: 27.0.11718014

Adding flag -DANDROID_PLATFORM=24 seems to fix the problem.
