Cmake how to avoid transitive linking of Target after policy cmp0022 set to new

I have library libB linked to libA using target_link_libraries(libA Interface libB).This libA is then linked to another libC like target_link_libraries(libC libA).



Now if my understanding is correct then if the cmp0022 is set to new then libC is transitively linked to both A and B, but I don't want it to happen for some targets as while building I'm getting some unresolved symbols error.



These errors are from targets that are transitively linked. How can it be solved?



Setting the policy back to old is not an option. Also linking the library as private is also not accepted as this issue is only for some targets. I tried getting the value of INTERFACE_LINK_LIBRARIES but is showing only those libraries that are directly linked not the one transitively linked. In which cmake property I can get this?

  • Linking with additional library cannot be source of "undefined reference" error. So your problem is somewhere else. Also, the policy CMP0022 is not about INTERFACE linking in whole, it is about configuration-specific interface linking.

count number of partitions of a set with n elements into k subsets

up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
