如何在C++中包含外部庫？

Question

我想將一個external library called SVL (simple vector library)包含到C++中。我遇到了很多麻煩。我正在使用Mac OSX，而​​該庫的README僅針對Windows。

我做

make clean 
make 

此創建的庫文件libsvl.a和libsvl.dbg.a。我看到在READMEof the file中，它表示將其包含爲svl/vec3.h左右用於不同的標題。但是，當我嘗試這樣做時，它不起作用，仍然說，

vertex.hh:9:10: fatal error: 'svl/Vec3.h' file not found 
#include <svl/Vec3.h> 
    ^
1 error generated. 
vertex.cc:10:10: fatal error: 'svl/Vec3.h' file not found 
#include <svl/Vec3.h> 

你能建議我什麼我錯過？我可能需要更好地定義圖書館的路徑或做一些不同的事情。

從其他代碼庫文件中的相對路徑是../svl-1.5/lib/libsvl.a

化妝配置文件

運行make

cd src && /Applications/Xcode.app/Contents/Developer/usr/bin/make REACTOR=.. 
c++ -O2 \ 
      -c LibSVL.cpp -I../include -I/sw/include 
c++ -O2 \ 
      -c Basics.cpp -I../include -I/sw/include 
ar rcu libsvl.a LibSVL.o Basics.o 
mkdir -p ../lib 
mv libsvl.a ../lib 
c++ -DDEBUG -g \ 
      -DVL_DEBUG \ 
      -c LibSVL.cpp -o LibSVL.do -I../include -I/sw/include 
c++ -DDEBUG -g \ 
      -DVL_DEBUG \ 
      -c Basics.cpp -o Basics.do -I../include -I/sw/include 

完全make文件的結果

# NOTE: To build multiple system libraries in AFS, make 'afs-setup' first. 
# This will create the necessary architecture-dependent lib directories,
